LUMINESCENCE DIODE CHIP WITH AN ANGLE FILTER ELEMENT |
摘要 |
The invention relates to a luminescence diode chip comprising a semiconductor body (1) producing radiation having a first wavelength, a luminescence conversion element (5) that produces radiation having a second wavelength from the radiation having the first wavelength, and an angle filter element (4) that reflects radiation that impacts said angle filter element at a particular angle relative to a primary emission direction back in the direction of the semiconductor body. |
